WHEEL-HUB AND To all whom it may concern:

-Be vit known that we, HERBERT KINTz andv JOHN P. MoCoNNEL, citizens'ofthe United States, residing at Sharpsburg and Pitts-I burg,respectively, in the county of Alle-J ghenyand State ofPennsylvania,have invented 'certain new and useful Improvements in Wheel-Hubs andlAxle-Bearings,

Our invention pertains to certain new and particularlyadaptable for usein connection with the wheel hubs and axle bearings, involving the useand arrangement of a resilient means to absorb or lessen the jar o rShock rimparted to the vehicle when running over uneven surfaces.

Our device will be especially l advantageous whenl applied tovehicles'of the automobile or motor driven class, or in fact any vehicleusing rubber tires, and aims to dispense with the expensive pneumatictires now commonly used.

It-will also be practical to employ our .devvice in connection withsteel tired vehicles.

The fundamental object of ourV invention is to provide a reliablecushioning device in conjunction with the hub and axle, whereby be takenup and absorbed by the resilient "In lthe accompanying drawings forminga partvof thisspecification Figure 1 is a fragmentai section of avehicle wheel showing exterior of enlarged hub for housing the re-'versesection of Ha wheel showing details of interior construction of thehub. Fig. 3 is.' a front elevation ofl the-hub with cap removed. Fig. 4shows one-half section of a verse section taken on the .line 5--5 ofFig.- 4; Fig. 6 is a transverses'ection ofV our resilient axle bearing,separate from the wheel, and supported by a bracket.

The pins-15 are of less length or extent than theradii of the interior concave surface of the drum 5, thereby providing aspace between the'endbf said pins and the said concave surface, forallowing limited play of the bearing blocks relative to the lsaid drum.A collar 19 seated over and securedto the axle serves as a washer toexclude dirt from the interior of the drum.

' The operation, and practical results obtained by the use of ourinvention, when the component parts are.. combinedfjandV assembledapproximately as shown and described, lwill be as followsz-The shockorjar imparted to the vehicle when running over uneven surfaces will beAtransmitted partly to the vehicle springs and -the remainder or surpluswill be taken 11p-'and absorbed by the resilient elements positioned inthe wheel hub or axle bearing, in the following manner: The variable.movement of the axles,

both frontand rear, when responding t0 the rise and fall kof the vehiclein running over uneven surfaces, will set up a vibratory action of theresilient elements. The limit of movement afforded to the axle in thehub, or hung bearing, by the apertures 8 and 11 will be sufficient tocause the tension memvbers responding to either slight or intenseshocks. No matter how slight the movement may be the axle will exerteither an upward or downward pressure on the bearing block segments, 12,said action tending to depress the spring members 16 which, when theshock has passed, will react and force the axle back to its normalcentralized position. Ihe ends of the pins 15, which will be shovedoutward during any movement of the axle, are also allowed a vlimitedfree lateral play between the shoulder bearings 18, the buffer plates orwashers 17,'being adapted to slide yon their bearings infthe event ofany such lateral movement. The axle 9 might be co sidered as. floatingin the hub, or bearing, and free to move in any direction, its fulllimit of movement however being overned the sizeof the apertures 8 an-11, and

A s v The form of wheel shown in Figs. land 2 -is intendedfor the front axle of arotor-vetion,or how the shock is imparted to theaxle f or wheels, the resilient elements will in/ stantly' g,-,respondto the movement of said- 6 5 axle, and as quickly subside when the jar ihicle, or for all four wheels of any other styles of vehicles. Invehicles of the motor driven class, where'the front wheels pun free andindependent of the axle, our resilient --beariY ing is constructed as,the wheel hub, but,for the rear it is'separate and apartfrom thewheels, and is positioned on the power .driven axle `inclose proximitytothe inner face of said rear wheels. Our bearing 'in the latterinstancewould'be supported by a suitable bracket 20, the upper portion of whichis se` cured to the vehicle springs. s v- What we claim asnew, andldesire to se' cure byI Letters Patent, is:

1. In a vehicle hub, an axle,beari'ng blocks rotatable on the axle, adruml concentric with the axle and having shoulders on its in nercircumferential surface land having U shaped apertures formed betweensaid shoul# ders, plates slidable on saidshoulders and each having ahole therethrough, radially disposed pins fixed to said bearing blocksvand entering said apertures through said.

holes, said pins being of less radial extent than the internal radii ofsaid inner surface,

to allow limited play of the bearing blocks relative to the drum, andsprings around saidpins interposed between said plates and said bearingblocks for absorbing Shock sub-l stantially as specified. 2. In avehicle hub, an axle, bearing blocks rotatable on the axle, a drumconcentric with the axle and having shoulders on its inner concavesurface and U-shaped'apertures between said shoulders, segmental platesspanning said apertures and `having slidable movement on said shoulders,each'plate hav? ing a Vhole therethrough, pins projecting from saidbearing blocks through said holes and entering said apertures, the freeends of said pins being normally spaced apart from the concave surfaceof said drum for the purpose specified, and springs interposed betweenthe bearing blocks and the plates for absorbing shock. y

In testimony whereofwe -aflix 'our signa- Itures in presence of twowitnesses.
